Question

giv the exact site address pleez help

Answer 1

They have a similar definition as us, but see in limited colours, because most of their senses is derived from hearing and smell.

In some respects, dogs can see far better than humans can. They have heightened peripheral vision and excellent night vision. Interestingly, dogs can sense movement much better than humans, but we see stationary objects more clearly than they do. Since dogs' ancestors hunted only things that moved, they had no need for good stationary eyesight.

Things sure look different from a dog's eye view. As a predator, the dog has binocular vision, but his eyesight is more attuned to movement than details. Dogs are red-green colour blind, Simply put, this is due to having only two cone types rather than three (light sensitive cells include cones and rods).

Their field of vision is cluttered with objects that are between a few inches and a few feet tall, hence distance is not judged quite as well. However, not needing to disguish ripe food, or distance allows thier eyes to have more rods (which enable night vision).
They also have a structure called the Tapetum Lucidum - a reflective surface behind the retina (area including the light sensitive cells) that reflects light back through it (gives the eerie shine at night).

Answer 2

There was a fabulous episode of Mad Labs on this topic, which comes on the discovery network. Different types of dogs have different eye sight. Some can watch TV as we can, some can't.

Your project, you find the site.

Good Luck.

Answer 3

Are you definite you are even allowed to test on refuge puppies like that? Also, technology reasonable tasks do not generally contain reside animals, it is too difficult. I've simplest visible one pre-institution/tuition challenge that used animals, and the group used fish.

Answer 4

Dogs do see in color according to newer studies, they only have trouble seeing greens and blues. Here's a couple of sites to help you:
